What is a gratin?

Basically a gratin is a dish, usually a vegetable of some kind, that is topped with a browned crust. The crust is usually made of bread crumbs and/or cheese. You’ve probably heard for potatoes au gratin. This is a twist, made with brussels. And it is absolutely divine.

What ingredients do you need to make Brussel Sprouts Gratin:

BRUSSELS SPROUTS: Cut in half. If the brussles sprouts are on the larger side, you can cut them in quarters. No need to do any other trimming!

OIL

SALT/PEPPER

BUTTER: salted or unsalted is fine.

SHALLOTS: Shallots will give a delicate onion flavor. You could use red onion in a pinch.

GARLIC

HEAVY CREAM: This is a decadent dish so don’t skimp out and use milk. Use the heavy cream!

GRUYERE CHEESE: The most common cheese used when making a gratin. It is a smooth melting Swiss cheese. It has a nutty, mild sweet flavor.

PANKO BREAD CRUMBS: I adore the crunch that panko bread crumbs add to dishes. It’s light and crunchy, perfect for the topping.

    We’ve never had brussels sprouts in a gratin before. Clearly, we’re going to change this! Also, I wouldn’t mind serving this goodness for Easter this year!

    FAQs

    Why do you soak brussel sprouts before cooking? ›

    The soak time tenderizes the sprouts so the middles are softer. Don't worry, they won't be soggy! I would never do that to you. If, like me, you don't mind some chew to your sprouts, you don't need to soak the Brussels sprouts prior to cooking.

    What takes the bitterness out of brussel sprouts? ›

    A splash of lemon juice, or even apple cider vinegar, works wonders on bitter sprouts.

    Should I parboil brussel sprouts before baking? ›

    Unlike other vegetables, Brussels sprouts can be parboiled (even a day ahead) to reduce the roasting time without hurting their texture.

    Why won't my brussel sprouts get crispy? ›

    Roast the Brussels Sprouts at high heat

    If you don't hear them crisping up in the oven, add a little more oil and roast them for a few more minutes until your desire crispiness is achieved!

    Why do you soak brussel sprouts in salt water overnight? ›

    For best results, soak your Brussels sprouts in salt water. Not only does salt act to tenderize the dense sprouts, but it will also help to season them all the way through. It won't take a lot -- just add 1 tablespoon of salt per 1 quart of water and toss in trimmed and halved Brussels sprouts.

    Is it better to blanch brussel sprouts before roasting? ›

    To guarantee great texture, do both! Trim and halve your brussels, then blanch and thoroughly dry them, and then roast at a high temperature until the outer leaves are starting to blacken. Moisture is the enemy of crispiness.

    Why do brussel sprouts smell bad when cooking? ›

    Yes, according to the Los Angeles Times, Brussels sprouts inherited another gene that causes them to stink up your kitchen when you cook them. When you cook Brussels sprouts they give off a gas: hydrogen sulfide. And if you are the least bit sensitive to smells, it will make you want to hurl.

    Why do my brussel sprouts taste like chemicals? ›

    The bitter taste of Brussels sprouts comes from compounds called glucosinolates and their degradation products, he explains. These bitter tasting compounds are an important part of the plant's defence mechanism against leaf-eating enemies, such as insects, nematodes, slugs, and herbivores, like pigeons and deer.

    Should you cut brussel sprouts in half before cooking? ›

    One of the most common ways to cut a Brussels sprout is in half or quarters. By doing so, you reduce the size of the sprouts, speeding up cooking.

    How long do you blanch brussel sprouts for? ›

    Bring a large pot of water to a boil and fill a large bowl with ice water. Blanch small Brussels sprouts for 3 minutes, medium for 4 minutes, and large for 5 minutes. Plunge the blanched sprouts in the ice water to stop the cooking process then move them to a clean towel and pat dry.

    Can dogs have brussel sprouts? ›

    Yes, dogs can eat Brussels sprouts, but they should be cooked and served in moderation. Brussels sprouts are rich in vitamins K, A, and C beneficial for dogs. Some dogs may not like the bitter taste of Brussels sprouts. Never feed your dog raw Brussels sprouts as they can cause digestive issues.

    Are brussel sprouts better steamed or boiled? ›

    Steaming Brussels sprouts preserves more of the nutrients and antioxidants than any other cooking method. And they turn out tasting like crisp-tender, sweet little nuggets. Plus they're just about the quickest veggie side dish you can cook.

    How does Jamie Oliver cook brussel sprouts? ›

    Place the Brussels in a large saucepan over a high heat for a couple of minutes, then, once the pan is nice and hot, cover with boiling salted water. Boil for 5 minutes, or until just tender but with a little bite. Taste to check – they should be slightly undercooked.
